El Sancho: Why I am a Mexican Man

I was listening to an NPR discussion on life insurance in minority communities (because NPR can make even this subject interesting to me, which is why I should donate some cash).  The insurance expert explained that a major reason Mexican men won't buy life insurance is El Sancho.  El Sancho is the guy your wife takes up with after you're dead and who will spend all your life insurance money.  I've always been bothered by the possibility that a second wife could spend IRA money I accrued before I got married.  Now I have a name for it!
